BOSCH, DECEASED.

To all whom (it man concern: w I I Be it known that I, WILLIAM E. BURKE, a citizen of the United States, residing at; Lorain, inv the county of Lorain and State of Ohio, have invented new'and useful Ini- PIOVBIHGHBSIH Valves for Flushing-Tanks, of which the following is a specification:

The present invention has reference to flushing tanks and like apparatus wherein the main or inlet valve is operated by a fluid-controlled device which is ordinarily in the form of a float-lever.

It proposes, briefly, improved means for imparting a positive initial movement in one direction, to assistthe action. of the float-lever and thus insure the certainty and rapidity of operation of the apparatus.

An embodiment of the invention is illustiated in the accompanying drawing, whereo Figure 1 is a vertical sectional view Show ing the said invention appliedv to a flushing tank; Figs. 2 and 8 are enlarged longitudinal sectional views showing the valve in open and closed position, respectively; and Fig. 4 is a transverse section taken on the line el4 of Fig. 2.

In said drawing, 5 indicates, generally, a flushing tank of ordinary construction, furnished with the usual inlet and overflow pipes 6 and 7 The inlet pipeis equipped with a controlling device 8, here shown as in the form of a bib, whose inlet portion 9 is fitted directly upon the end of said pipe. The cylindrical body portion 10 of said bib constitutes a casing whose inner wall is. provided with left-hand screw-threads11 and is further provided with a longitudinal slot 12, the inner end of said slot producing a shoulder 13.

At the inner end of the casing is located the valve seat 14:, which latter is formedin the usual partition 15 and serves as the means of connection between the aforesaid inlet 9 and the outlet or discharge spout 16. The valve 17, which cooperates with said seat, is carried by the stem 18 and is formed with an externally-threaded enlarged porvatvnroa F Us ING-TANKS. H 1" fi'oat-lever 21 are imparted directly. to the valve steni 18, as will beundei'stood, and the latter, on being rotated, will thusseat or unseat the valve. i I

'2 i lever" to drop and thus-rotate the-valve stem 1 ;1n a clockwise-direction,'Fig. g withkthe, r'ethreaded portion thereof binding in the corresponding portion ofthe bore of the eastive initial movement to the valve away from its seat, when the flushing operation takes place. The means for producing this initial movement is here shown as constitutedby an expansible coilspring 23 which 111g, means is provided for imparting a posiencircles the valve stem and bears at one end against the shoulder 13 produced by the formation of the slot 12, into which slot the end in question'extends, asdepicted in Figs, 2 and 3. Theiother end of the spring is bent laterally and'inserted into an opening 24: formed transversely through the valve stem. In consequence of this arrangement, the aforesaid spring willbe normally com pressed, owing to the normally raised position of the float-lever, but as soon as the latter starts to drop, the spring will immedi- 1 ately expand and thus rotate the valve stem clockwise. thus loosening the threadedportion 19 of the valve in the threadedportion of the bore and moving the valve a slight distance awayfrom its seat. Continued ClOGkWlSB'lOttLtlOIl of the valve stem lIlCldental to the dropping of the float-lever will In order to prevent splashing of the water i thus discharged through the spout, the latter may be expanded at two portions re mote from each other, as indicatedby the numerals 25, 25, the portion intermediate these expanded portions, and also the .6X I I treme end of the spout being contracted, as

indicated by the numerals 26, 26. In this way the water will be caused to flow with.

less force into the tank. The bib mav further be provided with a vertical pipe 27 whose lower end fits in thebore of a lug or boss 28 that is constructed upon the spout and opens into the latter, the upper portion of the pipe being ormed with a crook that projects downwardly into the overflow pipe 7 The water flowing through this pipe 27 into the overilow pipe serves to reseal the.

one end thereto and engaged at the other end bowl, as will be understood.

- I claim r i 1. The combination, with avalve casing having an internal valve seat and an interiorly-threaded bore leading to said seat and provided with a longitudinal slot; of a Valve threaded in said bore and provided with a stem; an operating lever connected to said stem; and a normally compressed spring having one end engaged in said slot and the other end connected to said stem,' and tending to rotate the latter in one direction, to unseat said valve.

2. The combination, with a flushing tank and its water-inlet pipe; of a bib attached I with a valve seat; a valve threaded in said casing and provided with a stem; a floatleverconnected'to said stem for rotating the same to seat and unseat said valve; and a spring encircling said stem and connected at with said wall, said spring being compressed by the rotation of said stem incidental to the upward movement of said float-lever, whereby it will normally tend to automatically rotate said stein in the opposite direction and unseat said valve.

In testimony whereof I have hereunto set my hand 1n presence of two subscriblng witnesses. 7 WILLIAM E. BURKE. Witnesses:
